TO ALL WHOM IT MAY CONCERN:

Be it known that I, C. CON'KLING, of Ashland, in the county of Ashland, and State of Ohio, have invented certain new and useful improvements in Envelopes; and I do hereby declare that the following is a full and complete description of the construction ofthe same, reference being had to the accompanying drawings,

making a part'of this specieation, in which- Y Figure 1 is afront viewof the envelope without the belt.

Figure 2 is a view with the belt passed through the loops.

Figure 3 is a view with the belt folded together and sealed.

Figure 4, a View of the opposite side of the envelope, showing the loops.

Figure 5 is aview of the' same, with the duplicate back.

Figure 6 is a perspective view.

Figure 7 is a detached View.

Lilie letters of reference refer to like parts in the several views.

This envelope isnnade in the ordinary way and shape, as shown, with the additions which will be referred i to in the description.

In fig. 1, B represents a wire. loop, one side of said loop passing under the lap A of the envelope, and held down by pasting said lap in the ordinary way, or it can be fastened to a piece indicated by` the 'dotted lines a in fig. and pasted down. The loop C is fastened to the upper lap A of the envelope, passing the lap through.

,the loop, and past-'ing the edge down on the under side of the lap, es shown ing. 7. Thus the two loops are fastened to the envelope and held in position. The belt D, fig. 2, can then be' passed through thelocps, as showt, and the la-ppels D of said belt folded, as shown in iig. 3, when it can be sealed and stamped, and the address, if wished, can be pntl on this belt. Fig. 4 is a View of the back of the envelope.l E E are wire loops, by means of which the duplicate backs are held in place. The ends of these wires pass through the back of the envelope, and are bent down on the inside, so as to secure them in place; the back F is then put on, 'and the ends turned under the wire between the duplicate back'and back of the envelope, as indicated by the dotted lines a in iig. 5; the address to be put on the duplicate back. This envelope can be made with two loops for the belt, or two for the belt and two for the back, as desired, either with two or four loops. As a repeating envelope it can be used again and again; also, as a letter envelope, it will aord the postal revenue additional 'security against fraud in the second use of the postage stamps, as in opening the envelope it has to be eut through the belt, if the envelope is to be used again, and the stamp which is on said belt .will have to be cui with it. Thus it supplies the place for a post mark, postage stamp, lettei` address, and to seal the envelope. When the gummed belt l) is destroyed by opening the envelope, another can bereplaced on reversing said envelope, and the duplicate back is to bear the letter address. When the belt is not used, which is optional, the back is to be destroyed, and another replaced, when the envelope is to be used again, as the belt before5 described. These envelopes can be of any size, to send as many letters as required in one, and can be made large and strong enough for express packages-a large` oneis shown in iig. 6. The nature of my invention admits of its being applied toeenvelopes of various forms and sizes. The imprinted belt it will be impossible to manage for purposes of fraud. The belt, with a stamp, will preclude fraud also, for the reason that it preclildes the facility` of it to such an extent that no advantage can be gained by it. i

What I claim as my improvement, and desire to secure by' Letters Patent, is-

1. The belt D and loops B C, in combination with the envelops, substantially as described.

2. The llnplicate back F and loops E and envelope, substantially as and for the purpose set forth.

3. The `nplicate back F, in combination with the en'velopebns and for the purpose set forth.`

4. The self-sealing belt D, in combination with the envelope, as and for the'pulpose set forth.
